Awww your dog looks such a sweetheart.... I'll be sure to say extra prayers tonight so that all continues to go well for your "Lil Angel" My Cavalier that I had some years ago had to have hip surgery so I know all about what your going through trying to make them stay calm and everything which is not an easy thing to have to do for such an active dog... Meds work wonders though and in no time at all I'm sure they will be getting along just fine...

~Peace & Blessings to ya both~
